Student Switch Off is harnessing student silliness to take simple steps to save energy, including wrapping up warm, switching off lights and using lids on saucepans, so helping participating UK universities to keep a lid on their fuel costs. Through its inventive use of social media, peer-to-peer engagement and student-focused incentives, this exciting initiative last year helped participating universities cut their electricity consumption by over 7%. Some 43 universities and 18,000 students are involved so far.
